Security information Siemens provides products and solutions with industrial security functions that support the secure operation of plants, systems, machines and networks.

In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens' products and solutions constitute one element of such a concept.

Customers are responsible for preventing unauthorized access to their plants, systems, machines and networks. Such systems, machines and components should only be connected to an enterprise network or the internet if and to the extent such a connection is necessary and only when appropriate security measures (e.g. firewalls and/or network segmentation) are in place.

For additional information on industrial security measures that may be implemented, please visit (http://www.siemens.com/industrialsecurity).

Siemens' products and solutions undergo continuous development to make them more secure. Siemens strongly recommends that product updates are applied as soon as they are available and that the latest product versions are used. Use of product versions that are no longer supported, and failure to apply the latest updates may increase customers' exposure to cyber threats.

You can find the tables of measuring ranges and overflow, overrange, etc. in the section Representation of analog values in the current measuring ranges (Page 38) and the "Analog value processing" function manual.

Parameters/address space 4.2 Parameters


4.2 Parameters

Parameters of AI 2xI 2-/4-wire ST During configuration of the module with STEP 7, define the properties of the module via various parameters. The following table lists the configurable parameters. The effective range of the configurable parameters depends on the type of configuration. The following configurations are possible:

Central operation with an ET 200SP CPU

Distributed operation on PROFINET IO in an ET 200SP system

Distributed operation on PROFIBUS DP in an ET 200SP system

When assigning parameters in the user program, use the "WRREC" instruction to transfer the parameters to the module using the data records; refer to section Parameter assignment and structure of the parameter data record (Page 32).

The following parameter settings are possible:

No Module Module

1 Due to the limited number of parameters at a maximum of 244 bytes per ET 200SP station with a PROFIBUS GSD configuration, the configuration options are restricted. The parameter length of the I/O module is 4 bytes for PROFIBUS GSD configuration. If necessary, you can set this parameter by using the data record 128, see the appendix "Parameter data record".

2 The settings in the "Interference frequency suppression" parameter have a direct effect on the conversion time of the channel. The analog value is therefore also affected by additionally set filtering via the "Smoothing" parameter.

3 Interference frequency suppression: Noise at 400 Hz is automatically included in the filtering at 50 Hz.

Parameters/address space 4.3 Description of parameters


Note Unused channels

"Deactivate" the unused channels in the parameter assignment.

A deactivated channel always returns the value 7FFFH.

4.3 Description of parameters

Diagnostics: No supply voltage L+ Enabling of the diagnostics alarm for no or insufficient supply voltage L+.

Diagnostics: Short-circuit to ground Enabling of the diagnostics in the event of a short-circuit of the encoder supply to ground or of an input to the encoder supply.

The short-circuit and underflow diagnostics can be activated simultaneously. If both diagnostics events occur simultaneously, the short-circuit diagnostics is output.

Diagnostics: Overflow Enabling of the diagnostics when the measured value exceeds the overrange.

Diagnostics: Underflow Enabling of the diagnostics when the measured value falls below the underrange.

Diagnostics: Wire break Enabling of the diagnostics if the module has no current flow or has too little current for the measurement in the range of 4 mA to 20 mA.

The wire break and underflow diagnostics can be activated simultaneously. If both diagnostics events occur simultaneously, the wire break diagnostics is output.

Measurement type/measuring range See the section Measurement types and measuring ranges (Page 16).



Smoothing The individual measured values are smoothed by filtering. The smoothing can be set in 4 levels.

Smoothing time = Number of conversion cycles (k) x conversion time (≙ of the integration time set in the "Interference frequency suppression" parameter) of the channel.

The following figure shows how many conversion cycles it takes for the smoothed analog value to approach 100%, depending on the configured smoothing. This applies to every signal change at the analog input.

① No smoothing ② Weak (k = 4) ③ Medium (k = 8) ④ Strong (k = 16)

Figure 4-1 Smoothing for AI 2×I 2-/4-wire ST

Interference frequency suppression Suppresses the interference affecting analog input modules that is caused by the frequency of the AC voltage network used.

The frequency of the AC voltage network can negatively affect the measured value, in particular when measuring in the low voltage range and with thermocouples. With this parameter, the user specifies the line frequency that is predominant in the plant.

Note:

The interference frequency suppression works parallel to the sampling of channels 0 and 1. The cycle time of the module is 500 μs regardless of the number of channels used and the configured interference frequency suppression.



Potential group A potential group consists of a group of directly adjacent I/O modules within an ET 200SP station, which are supplied via a common supply voltage.

A potential group begins with a light-colored BaseUnit through which the required voltage is supplied for all modules of the potential group. The light-colored BaseUnit interrupts the three self-assembling voltage buses P1, P2 and AUX to the left neighbor.

All additional I/O modules of this potential group are plugged into dark-colored BaseUnits. You take the potential of the self-assembling voltage buses P1, P2 and AUX from the left neighbor.

A potential group ends with the dark-colored BaseUnit, which follows a light-colored BaseUnit or server module in the station configuration.

Parameters/address space 4.4 Address space


4.4 Address space

Configuration options The following configurations are possible:

Configuration 1: Without value status

Configuration 2: With value status

Evaluating the value status If you enable the value status for the analog module, an additional byte is occupied in the input address space. Bits 0 to 1 in this byte are assigned to a channel. They provide information about the validity of the analog value.

Bit = 1: There are no errors on the module.

Bit = 0: Channel is deactivated or there is a fault on the module.

If a fault occurs on a channel with this module, the value status for all channels is 0.

Address space The following figure shows the assignment of the address space for the AI 2xI 2-/4-wire ST with value status (Quality Information (QI)). The addresses for the value status are only available if the value status is enabled.

High limit violated 7H Value is above the overrange. Correct interplay between module and encoder

Low limit violated 8H Value is below the underrange. Correct interplay between module and encoder

Error 9H Internal module error has occurred (diag-nostics alarm on channel 0 applies for the entire module).

Replace the module

Parameter assignment error

10H • The module cannot evaluate parame-ters for the channel.

• Incorrect parameter assignment.

Correct the parameter assignment (wire break diagnostics set only with the permitted measuring ranges).

Supply voltage missing 11H Missing or insufficient supply voltage L+ • Check supply voltage L+ on the BaseUnit

• Check BaseUnit type

Channel temporarily unavailable

1FH Firmware update in progress or update has been canceled. The module does not read any process values in this state.

• Wait for firmware update. • Restart the firmware update.

1 Since the module has no encoder supply for separate channels, a short-circuit in a channel has a permanent effect on the other channel.

Parameter data record A.2 Parameter assignment and structure of the parameter data record


A.2 Parameter assignment and structure of the parameter data record

Parameter assignment in the user program You can reassign the module parameters in RUN. For example, the voltage or current values of selected channels can be changed in RUN without having an effect on the other channels.

Changing parameters in RUN The "WRREC" instruction is used to transfer the parameters to the module using data record 128. The parameters set in STEP 7 are not changed in the CPU, which means that the parameters set in STEP 7 will be valid again after a restart.

Output parameter STATUS The module ignores errors that occur during the transfer of parameters with the "WRREC" instruction and continues operation with the previous parameter assignment. The STATUS output parameter contains a corresponding error code.

You will find a description of the "WRREC" instruction and the error codes in the STEP 7 online help.

Structure of data record 128 for entire module

Note

Channel 0 includes the diagnostics enable for the entire module.

Header information The figure below shows the structure of the header information.

Figure A-2 Header information

Parameters The following figure shows the structure of the parameters for channels 0 and 1.

You enable a parameter by setting the corresponding bit to "1".

Error transmitting the data record The module always checks all values of the transmitted data record. The module applies the values from the data record only when all values have been transmitted without errors.

The WRREC instruction for writing data records returns the appropriate error codes if there are errors in the STATUS parameter.

The following table shows the module-specific error codes and their meaning for parameter data record 128.

rameter (hexadecimal)

Meaning Solution

Byte 0 Byte 1 Byte 2 Byte 3 DF 80 B0 xx Number of the data record unknown Enter valid number for data record. DF 80 B1 xx Length of the data record incorrect Enter valid value for data record length. DF 80 B2 xx Slot invalid or unavailable • Check the station to determine if the

module is plugged in or pulled. • Check assigned values for the parame-

ters of the WREC instruction.

DF 80 I0 xx Incorrect version or error in the header information

Correct the version, length and number of parameter blocks.

DF 80 I1 xx Parameter error Check the parameters of the module.


Representation of analog values B B.1 Representation of analog values for analog inputs

This appendix shows the analog values for all measuring ranges that you can use with the analog module.

Measured value resolution The resolution of the analog values differs depending on the analog module and its parameter assignment.

The table below shows the representation of binary analog values and of the associated decimal and hexadecimal units of the analog values.

Each analog value is written left aligned to the tags. The bits marked with "x" are set to "0".
